I always suggest preventative maintenance first. Has the Killer dowel pin been slain yet? Thats what I did first to my 91.5 because that can leave you on the side of the road. Next would be guages, then exhaust, then better intake, then mess with the pump and timeing for free power (more fuel). 3200 gsk is the best $20 I've spent on the truck. See how well you like it from there

Definitely get some gauges and when I got mine i went through and changed all the fluids just so I knew what I had. The 3200 governor spring like cumminsfreak said is a must and only a 20 dollar investment. There's all kinds of directions and drawings of how to tweak the pump on here in this section. Look around and enjoy the new ride
